How a pregnant mother’s diet could change a child’s brain

Scientists have pursued every possible avenue to try to figure out why we keep getting fatter. They’ve explored our genes, our brains, our hormones and our gut bacteria, not to mention our fatty, sugary diets and sedentary lifestyles. Now, a recent study has come out blaming our expanding waistlines and poor health on our parents’ behaviors before we were born.

My newest article is up on The Atlantic, discussing recent research on the impact a mother’s diet has on her offspring’s health, affecting our brains and subsequently our bodies. This line of research isn’t new — otherstudies have shown links between a woman’s health during pregnancy and her child’s weight later in life — but this is one of the first to provide a potential explanation for this phenomenon by looking in the brain at some crucial hunger hormones.

However, you can’t blame all of your problems on your parents; what you eat still has a major impact on how these brain changes manifest:

Now, I’m all for shifting blame away from myself and onto my parents, but I feel that, like every possible explanation behind the obesity epidemic, this is only one piece of the puzzle. Genes undoubtedly play a role in body mass, fat percentage, and metabolism, but so does what you eat and how many calories you burn through physical activity…The problem of obesity, like so many health and social issues we face today, is that there isn’t just a single contributor to the problem. If there were, it would have been solved by now.
